There are some that are listed in the publication. A rotary plate is mounted on a moving member that can move along a straight line, and a plurality of cam rollers provided on the rotary plate are sequentially engaged with recesses in the cam plate, thereby causing the rotary plate to rotate. It's something we're used to being forced to do. Rotating devices using a rack and pinion are also known. However, these rotating devices have a problem of complicated structures and high manufacturing costs.

のである。 When changing the direction of an object to be transported using a rotation device, it is desirable that the object to be transported be rotated at a constant speed. This is because if the rotational angular velocity of the rotating device is irregular, acceleration will occur, and the position of the transported object may shift or the transported object may fall off from the rotating device. The curve shown in Figure 7 shows the point P when the center O of the circle moves at a constant speed on the straight line OA, and the straight line OP connecting the center O and a point P on the circumference rotates at a constant speed. is the locus, and the center of the circle O
is the rotation axis (rotation center line) 114 of the rotating member 102 in the above embodiment, and point P is the center point of the cam follower 104, then the ideal curve that the cam follower 104 should follow in order for the rotating member 102 to rotate at a constant speed is Become. 9 is a cam curve that the cam follower 104 should follow, and if the inclination angles of the first cam surface 108 and the second cam surface 112 are respectively approximated to the cam curve, the rotating member 102 can be rotated at approximately constant speed. The rotating device 100 in FIG. 10 has a cam surface 10
8 and 112 to approximate the central portion of the cam curve to rotate the rotating member 102 at a constant speed.

た。Problems to be Solved by the Invention However, since the cam surfaces 108 and 112 are straight lines, it is inevitable that the approximation to the smooth folded portion at the center of the cam curve is poor. Therefore, in this folded portion, that is, in FIG. 10, the cam follower 1
At the portion where 04 transitions, the rotational speed of the rotating member 102 changes rapidly, causing a large acceleration,
There were cases where it was not possible to successfully change the direction of the transported object.

度が生ずることが殆どない。 Counterclockwise rotation of the rotating member 56 is prevented by contact between the stopper surface 88 of the second cam 80 and the pin 74. Since the stopper surfaces 87 and 88 are parallel to the moving direction of the support column 44, the rotating member 56 moves linearly while being prevented from rotating in both directions. The first cam surface 82 and the second cam surface 84 have the same inclination angle as the cam surfaces A and B, respectively, which approximate the ends of the ideal cam curve shown by the two-dot chain line in FIG. Since this portion is the closest to a straight line in the cam curve, it is possible to approximate the ideal cam curve with sufficient accuracy even if a straight cam surface is used. In other words, the rotating member 56 can be rotated at a constant speed.
In this rotating device 54, since the rotating member 56 is configured to rotate 90 degrees by the two pins 72, 74 and the two cam surfaces 82, 84, the pins 72, 74
moves in a manner that closely approximates the ideal curve, with almost no acceleration occurring along the way.

Use the surface symmetrical to 4 as the cam surface, and
It is also possible to move the support column 4 to the left, in which case the support column 44 will move while always maintaining a position behind the pins 72, 74, and 76.

向に沿つて塗装が良好に行われる。 When the truck 12 is run by the chain conveyor 16 and the bumper 46 is transported to the place where the spraying work is performed, the truck 12 is in a state of running on the guide rail 70 by the wheels 66, and the carrier roller 34 and the guide rail 36 are connected to each other. The engagement will come off.
As a result, the bumper 46 is transported while being accurately positioned.
is in a posture that extends long in a direction perpendicular to the conveyance direction, and both end faces in the longitudinal direction are coated by coating devices disposed on both sides of the conveyance roller. After this painting is completed, the pin 72 of the rotating device 54 and the first cam surface 82 engage, and the rotating member 56 begins to rotate. Normally, a meshing member 58 that is integral with the rotating member 56 meshes with a meshing member 59 to prevent rotation of the rotating member 56, but if a torque above a certain level is applied to the rotating member 56, the support 44 The meshing members 58 and 59 are disengaged while pushing up. By the time the engagement between the pin 72 and the first cam surface 82 and between the pin 74 and the second cam surface 84 is completed, the rotating member 56 has been rotated 90 degrees around the post 44, and the bumper 46 on the post 44 has also rotated 90 degrees. Rotated degrees. Since this rotation is approximately constant speed rotation, the bumper 46 does not move on the jig 52 or fall from the jig 52. Therefore, after the bumper 46 assumes a position in which it extends long in the conveying direction, painting can be performed satisfactorily along its longitudinal direction.
